Dupla Ground nature Los Nevados 5 kg, 2-8 mm

Natural stone for the freshwater aquarium and the terrarium. Los Nevados is rounded river gravel, grain size 2-8 mm, pack 5 kg.

A general-purpose grain: this is the grain size most community aquariums are set up with. Plant roots get support, water circulates through the bed, and dirt does not sink so deep that a gravel cleaner cannot reach it.

A natural product: this is natural stone and it is not dyed. The manufacturer notes that natural stone may contain traces of lime: if the tank water is meant to stay soft, test a sample before use (put a handful in water and follow the carbonate hardness for a few days).

How much is needed: the manufacturer's formula is tank length (cm) × width (cm) ÷ 140 = kilos for a five centimetre layer. This 5 kg pack therefore covers about 700 cm² of floor area at 5 cm. For example, a 5 cm layer in a 100 × 40 cm tank takes about 28.6 kg.

Setting up: rinse with cold water before use – transport creates fine dust that would otherwise cloud the water. The recommended layer is 5–8 cm depending on the planting.
